肝脏是维持生命不可缺少的器官之一,在人体生命活动中占有十分重要的地位。它不仅是蛋白质、糖、脂肪等代谢的重要器官,也是胆红素代谢、人体解毒作用和排泄某些物质的主要场所。故有人形象地比喻“肝脏是人体的最大化工厂”。在各种原因所致的原发或继发性肝损害时,肝功能可能异常。但因肝脏本身是一个再生力很强和储备力很大的器官,而每一种肝功能试验又比较局限,只能代表肝功能的某一侧面,故只有当疾病严重,肝细胞受到很大程度的损害时,才有可能明显地表现出异常来。又因各种疾病时,肝脏损伤部位程度和进展阶段的不同,肝功能的变化也有很大差异。因此对每一次肝功能试验结果,必须结合临床各种资料, Liver is one of the indispensable organs of life, occupying a very important position in human life and activity. It is not only an important organ of metabolism such as protein, sugar and fat, but also the main site of bilirubin metabolism, human detoxification and excretion of certain substances. Therefore, some people vividly metaphor “the liver is the body’s largest chemical plant.” Liver function may be abnormal when primary or secondary liver damage is caused by a variety of causes. However, since the liver itself is a very regenerative and well-stocked organ, each of the liver function tests is limited and represents only one side of liver function. Therefore, only when the disease is severe and the liver cells are greatly affected When the degree of damage, it is possible to clearly show abnormalities. Because of various diseases, the degree of liver damage and stage of progress of different stages of liver function changes are also very different. Therefore, every time the results of liver function tests, clinical data must be combined,
